I’ve got the opportunity of borrowing a coil shock to try out on my 5 Spot but it’s 200mm eye to eye with 57mm stroke as opposed to 190mm x 50mm standard

I’ve checked with a bit of square tubing with the right size holes with 200mm between centres and it will go in with the suspension slightly extended.

If I try this will it kill my frame or will I just need to run it with a bit more sag to take into account the extra length

Cheers for any assistance

Shouldn’t cause any problems as it’s longer when bottomed out than the old one.

It will steepen the bike a bit but youwill get a feel for coil, and let’s be honest, if you go back to air, we’ll know something new about you 😛

fully compressed, it’ll be longer than your existing one which means your tyre won’t foul the frame

no idea what it’ll do to forces on the frame – doubt it’ll be that big a change (IR not engineer)

unless you do run more sag, the “resting” geometry would be affected a bit (tiny bit steeper at the front, tiny bit slacker seat tube ?)

(ed

tiny bit slacker seat tube

WTF – that’d be unlikely, hey – since they’re both welded together)

Take the spring off and sit on the bike to see if the tyre fouls the seatube, static it’ll steepen the h/a, s/a and lift the bb a bit, sagged it may be ok, if your using the push rockers with an extra 7mm stroke the travel will go from 5.75inchs to roughly 6.7inchs (eg, leverage ratio is 3-1 then 3×2.25=6.75)
